Assign the values of one array to another not merging - php

Question

I need to append certain values of Second array to the first array
I.e.,
In the First Array i create two elements such as name and price and get the values from Second Array and give it to first array
Here is my First Array
[
{
"id": 8,
"user_id": 21,
"category_id": 1,
"juice_id": 2,
"count": "100",
"status": "1",
"created_at": "2016-02-23 07:12:14",
"updated_at": "2016-02-23 07:12:14"
},
{
"id": 9,
"user_id": 21,
"category_id": 1,
"juice_id": 1,
"count": "100",
"status": "1",
"created_at": "2016-02-23 07:15:47",
"updated_at": "2016-02-23 07:15:47"
}
]
And the Second array is
{
"1": {
"id": 2,
"store_id": 1,
"category_id": 1,
"name": "Cashew Butter Baby",
"image": "http://greenhoppingbucket.s3.amazonaws.com/juice/1455719144rebV3iRUlj.png",
"description": "Cashew, Butter and Milk",
"price": "12.00",
"status": 1,
"created_at": "2016-02-17 19:56:11",
"updated_at": "2016-02-17 19:56:11"
},
"2": {
"id": 1,
"store_id": 1,
"category_id": 1,
"name": "Kalekolada",
"image": "http://greenhoppingbucket.s3.amazonaws.com/juice/1455719105WAVB3SGxT7.png",
"description": "Pulp of Kale",
"price": "10.00",
"status": 1,
"created_at": "2016-02-17 19:55:34",
"updated_at": "2016-02-17 19:55:34"
}
}
My Expected result is
[
{
"id": 8,
"user_id": 21,
"category_id": 1,
"juice_id": 2,
"count": "100",
"status": "1",
"created_at": "2016-02-23 07:12:14",
"updated_at": "2016-02-23 07:12:14"
"name": "Cashew Butter Baby",
"price": "12.00",
},
{
"id": 9,
"user_id": 21,
"category_id": 1,
"juice_id": 1,
"count": "100",
"status": "1",
"created_at": "2016-02-23 07:15:47",
"updated_at": "2016-02-23 07:15:47",
"name": "Kalekolada",
"price": "10.00",
}
]
I tried to do $newArray = array_merge($cartData, $juiceData);
But it is simply merging two arrays.
What is the mistake and how can i do that ?

Here's some code for merging those arrays. You should have a common index for them though (a different order may lead to unexpected behavior).
<?php
$a = array(
array(
"id" => 8,
"user_id" => 21,
"category_id" => 1,
"juice_id" => 2,
"count" => "100",
"status" => "1",
"created_at" => "2016-02-23 07:12:14",
"updated_at" => "2016-02-23 07:12:14"
),
array(
"id" => 9,
"user_id" => 21,
"category_id" => 1,
"juice_id" => 1,
"count" => "100",
"status" => "1",
"created_at" => "2016-02-23 07:15:47",
"updated_at" => "2016-02-23 07:15:47"
)
);
$b = array(
array(
"id" => 2,
"store_id" => 1,
"category_id" => 1,
"name" => "Cashew Butter Baby",
"image" => "http://greenhoppingbucket.s3.amazonaws.com/juice/1455719144rebV3iRUlj.png",
"description" => "Cashew, Butter and Milk",
"price" => "12.00",
"status" => 1,
"created_at" => "2016-02-17 19:56:11",
"updated_at" => "2016-02-17 19:56:11"
),
array(
"id" => 1,
"store_id" => 1,
"category_id" => 1,
"name" => "Kalekolada",
"image" => "http://greenhoppingbucket.s3.amazonaws.com/juice/1455719105WAVB3SGxT7.png",
"description" => "Pulp of Kale",
"price" => "10.00",
"status" => 1,
"created_at" => "2016-02-17 19:55:34",
"updated_at" => "2016-02-17 19:55:34"
)
);
// For this to work the arrays need to have the same string keys
// $merge = array_merge_recursive( $a, $b );
$merge = array();
foreach( $b as $key => $entry ) {
if( isset($a[$key]) ) {
$entry += $a[$key];
}
$merge[] = $entry;
}
var_dump( $merge );
EDIT:
New info in comments would give us something like:
$categories = array();
foreach( $b as &$entry ) {
$categories[$entry['id']] =& $entry;
}
$products = array();
foreach( $a as &$entry ) {
if( isset($categories[$entry['juice_id']]) ) {
$entry['category'] =& $categories[$entry['juice_id']];
}
$products[] =& $entry;
}
var_dump( $products );
No need to pass them by reference but should save some memory.
